摘　　要：通过分析大众煤矿新副井马头门上下段井壁破坏的原因,结合近年来深井构造破碎带井壁支护的成功经验,对破坏段井筒及连接硐室采取了壁后深孔注浆、预应力锚索、U型钢井圈及支架、钢筋混凝土反拱、增加支护厚度、提高材料强度等多种支护措施,并取得了良好效果,可为同类井筒支护提供借鉴意义。Through the cause analysis of shaft lining damage in vertical section of new auxiliary shaft ingate in Dazhong Coal Mine,combining with the successful experience of shaft lining supporting in deep tectonic fracture zone in recent years,multi supporting measures were carried out in the broken shaft and connection chamber,including back wall deep hole grouting,pre-stressed anchor cable,U type steel reinforced concrete frame, reinforced concrete counter-arch,increasing support thickness,and improving the strength of the material,etc.,which achieved favorable results.
